## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 5.3.3
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

LPM treats this as warn-only first-party agent extension lifecycle risk. Installation can overwrite existing Todoist CLI skill files in several coding-agent configuration directories. It also performs a silent legacy-auth migration against Todoist.

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Installation can overwrite existing Todoist CLI skill files in several coding-agent configuration directories. It also performs a silent legacy-auth migration against Todoist.

- **Trigger:** npm installation or update runs the postinstall lifecycle.

- **Impact:** Existing agent instructions can change without an explicit CLI command; a legacy Todoist token is sent to the Todoist API for account migration.

- **Evidence paths:** package.json, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/index.js, dist/lib/migrate-auth.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-11T19:13:30.877Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Automatic update of existing agent skill files and legacy credential migration.

- **Rationale:** The automatic lifecycle mutation of pre-existing coding-agent skill files is a package-owned extension risk that warrants a warning. The inspected implementation is guarded, static, and Todoist-aligned, so it does not establish malicious behavior.

- **Files touched:** ~/.claude/skills/todoist-cli/SKILL.md, ~/.codex/skills/todoist-cli/SKILL.md, ~/.copilot/skills/todoist-cli/SKILL.md, ~/.cursor/skills/todoist-cli/SKILL.md, ~/.gemini/config/skills/todoist-cli/SKILL.md, ~/.pi/agent/skills/todoist-cli/SKILL.md, ~/.agents/skills/todoist-cli/SKILL.md

- **Network endpoints:** api.todoist.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The install lifecycle automatically imports the post-install module., Post-install updates every previously installed coding-agent skill, replacing its content., The updater targets Claude Code, Codex, Copilot, Cursor, Gemini, Pi, and a universal agent directory., Post-install also migrates a legacy Todoist token and sends it only to the Todoist user API.

- **Evidence against:** Skill updates occur only when the corresponding skill file already exists., The written skill is static package content, not a downloaded or executed remote payload., No shell execution, arbitrary code evaluation, or non-Todoist exfiltration was found in the inspected lifecycle path.

L101: const agentDir = join(homedir(), config.dirName);
...
L113: }
L114: await mkdir(dirname(filepath), { recursive: true });
L115: await writeFile(filepath, this.generateContent(), 'utf-8');
